Anyone who liked The Boat That Rocked might also like this wikipedia article about Radio Caroline — the ship-board pirate radio stations that (presumably) inspired that movie. It’s quite a remarkable history.

Note that although The Boat That Rocked was set in 1966, Radio Caroline was actually pop-centric station until they switched over to album rock in 1974.

You can still tune in an internet descendant of Radio Caroline populated by many of the marine-era djs, if you don’t mind your classic rock mixed up with ads for real estate agencies and gift shows.
